AAA型:既动词原形。过去式,过去分词三者同形。例如:let, set. hit .cut. put, shut .cost. hurt, read. spread2. AAB型:只有一个,beat-beat-beaten3. ABA型:既过去式与过去分词不同,但过去分词与原形相同。如:run. come, become. overcome(克服)4ABB型:既过去式与过去分词相同,而两者与原形不同。可分为下面六组:第一组:feel. keep. sleep weep sweep meet leave smell. deal spoil spill它们都以t结尾.第二组:spend lend send build都是变d为t第三组:lose get win shine dig hang都是变其中的元音字母。第四组:bring buy fight think catch teach都以ught结尾,其中catch, teach以aught结尾。第五组:tell sell lay pay say 都以“d”结尾第六组:无规律组,必须硬记.find stand understand sit have make hold hear mean5.ABC型:既过去式,过去分词与动词原形三者各不相同。第一组:在过去式上加 -n (注:过去式都是以“o辅音字母+e”结尾的,但rise除外) break-broke-broken choose-chose-chosen forget-forgot-forgotten(双写t) freeze-froze-frozen wake-woke-woken speak-spoke-spoken steal-stole-stolen 第二组 :在原形上加-n see-saw-seen give-gave-given drive-drove-driven take-took-taken draw-drew-drawn grow-grew-grown know-knew-known throw-threw-thrown blow-blew-blown show-showed-shown mistake-mistook-mistaken rise-rose-risen第三组:在原形上加 -en write-wrote-written(双写t) eat-ate-eaten fall-fell-fallen ride-rode-ridden (双写d) hide-hid-hidden(双写d) be-was/were-been第四组:符合 i-a-u的原则,并且发音规律相同。 begin-began-begun ring-rang-rung sing-sang-sung swim-swam-swum sink-sank-sunk(沉 ) drink-drank-drunk 第五组:bear-bore-born wear-wore-worn tear-tore-torn(流泪)第六组:lie-lay-lain(躺 ) do-did-done go-went-gone fly-flew-flown现在完成时的含义:(一)、它是过去发生的或已经完成的动作对现在造成的影响或结果。 1、表示过去发生的某一动作(该动作已经结束)对现在造成的影响或结果。例如:He has had his lunch.(强调结果,饱了)。又如:_-Have you done your homework?_-Yes, I have.(强调对现在的影响,其结果是作业已经完成了。)2、表示过去已经开始,并持续到现在的动作或状态,它往往与表示一段时间段for时间段,since过去的时间点连用I have taught here for more than two years. We have lived in this street since 1987. Since for的区别since后接时间点或表过去时的句子 如1993,last term, yesterday, the time I got there for后接一段时间表“长达多久”如ten years, a while, two days等。 用since和for填空 1. Jim has been in Ireland _ Monday. 2. His aunt has lived in Australia _15 days. 3. Mary is in her office. She has been there _ 7 oclock. 4. India has been an independent country _1974. 5. The bus is late. Theyve been waiting _ 20 minutes. 6. Mike has been ill _a long time. He has been in hospital _ October.(二)、特点:既涉及过去又联系现在,动作是过去发生的,其结果是现在存在的例如:She has come.(她来了)这句话说明两点:)她是过去某一时候来的)她现在仍然在这里,而且主要是说她在这里,动词用了现在完成时表示现在还存在过去的某一动作的结果或影响,至于她是什么时候来的,是十分钟以前还是一个小时以前,并不是
